(Cl. 137-4542)The present invention relates to improvements in valved pipe fittingsand the like which are particularly employed as hose couplers andwherein a male insert is provided in one conduit section for cooperationwith a female insert in a second conduit section. The presentapplication constitutes a continuation-in-part of my copendingapplication, now Patent No. 2,641,485, granted June 9, 1953, for ValvedPipe Fitting.

It is an object of the present invention to provide an improved recedingand rocking valve mechanism over the valved pipe fitting of the abovepatent application and wherein the improvements provide for longer lifeof the mechanism and wherein the improvements constitute safety featuresfor increasing the reliability of operation over my previously mentionedvalved pipe fitting of my prior patent.

Further objects of the present invention are to provide such valvedcoupler means that are particularly adapted for insert construction,thereby resulting in compact constructions and wherein the insert meansmay be of expendible character.

Still another object of the present invention is to provide an assemblywhich is so arranged that the operating parts alford visual supportwhereby the valved mechanism becomes a self-contained insert formounting in a conduit section or the like.

It is still a further object of the present invention to provide amechanism of the insert-cartridge type whereby the insert may beemployed with a great variety of pipe fittings, couplers, vessels, etc.,thereby making possible a higher degree of standardization, thusincreasing the possibility of mass producing the inserts and therebyreducing the cost.

Although the present insert construction appears to present a greaterobstruction to the flow of fluid therethrough as compared to the valvedpipe fitting of my prior patent, it will be observed that the insertconstruction requires a lesser outside diameter in its entirety with theconduit section whereby the opening through the insert is relativelylarger in proportion to the conduit opening. Thus, the opening throughthe insert-type of mechanism will be greater than the opening possiblethrough the valved mechanism of my prior patent when employed inconduits of similar cross-sectional area.

Various other objects and advantages will become apparent from thedetailed description to follow. The best form in which I havecontemplated applying my invention is clearly illustrated in theaccompanying drawings, wherein:

Referring more particularly to the drawings, wherein like numeralsdesignate like parts throughout, the numeral 10 designates generally thefemale insert while the numeral 12 designates generally the male insert,the numerals 14 and 16 represent the first and second conduit sectionswhile the numeral 18 designates generally a main line of supply for aplurality of pairs of conduit 19 are vertical longitudinal views takensubstantially along sections such as 14 and 16.

' The male insert 12 is substantially the same as that described in myprior patent, with the exception that the portions of the tube 20, seeFigures 3 and 4, on which the forwardly projecting lugs 22 and valvesupporting stops 24 are formed, are made substantially plain, parallelsurfaces, so that the inner distance between the lugs 22 or the stops24, as seen in Figure 3, is slightly less than the bore of the tube 20.In other Words, the poitions 26 and 28 of the tube 20 are inwardlyangulated and flat with a reinforcing cross member 30 joining the lugs22.- The male insert 12 is also formed with an elongated slot 32 whichis employed as an indexing means.

The female insert 10 is best seen in Figures 2,- 5, 6 and 9 through 11,and comprises a cylindrical shell 34, constituting the main body, andtwo rearwardly projecting cylinders 36 and 38 of reduced cross-sectionalarea, the pair of cylinders 36 and 38 being secured to the back plate40, which is in turn secured to the cylindrical shell 34.

Figure 7 shows the plate 40 as provided with a rim portion 42 and a pairof inwardly extending portions 44 and 46 having openings 48 and 50therethrough and for receiving the inner ends of the two, identicallyconstructed cylinders 36. The plate 40 has an enlarged opening 52 forfluid flow through the entire insert. The plate 40 is also provided witha plurality of longitudinal external notches 54 which are adapted toreceive projections 56, see Figure 5, rearwardly and axially extendingfrom the cylindrical shell 34. The uppermost notch 54 is employed as anindexing hatch to engage a suitable projection for fixedly positioningthe insert 10' within a coupler section such as section 14. I

The two cylinders 36, see Figure 5, are of open ended construction withone end portion turned in at 58 to provide a spring seat for the coilspring 60. The opp'os'ite end of each of the cylinders 36 reciprocablyreceives a plunger 62 which is outwardly urged by the coil spring 60.The plunger 62 has a reduced diameter portion 64 which is encircled by aportion of the coil spring 60 and the opposite end portion of theplunger 62 is formed with a recess 66 for a purpose to be hereinafterdescribed.

Disposed within the cylindrical shell 34 and secured thereto is a plate68, see Figure 8, of arcuate form and having substantially parallel sideflanges or walls 70 and 72. The arcuate portion of the plate 68 is inclose engagement with the internal surface of the shell 34 andpermanently fastened thereto, as by rivets 74.

As best seen in Figure 8, the arcuate plate 68 is provided with amedially and axially extending recess 76, for a purpose to behereinafter described, and an outwardly and rearwardly extending pair ofcam surfaces 78 and 80 extending from the recess '76 and terminating ina rearwardly projecting notch 82 at each side of the plate. Continuingfrom the notched portions 82, and extending downwardly along the forwardsection of the parallel flanges 70' and 72, are a pair of curved cammingsurfaces 84 and 86. The flanges 70 and 72 are also provided with cutoutportions which are substantially of the form of a rack tooth at 90 and92. The flanges 70 and 72 have integrally secured thereto the camelements 93 at opposite sides of the recessed portions 90 for providingadditional cam surface for taking up the wear. Pins 96 and 98 extendinwardly from the flanges 70 and 72 for a purpose to be hereinafterdescribed.

Rearwardly of the recesses 90, the downwardly projecting edges of theflanges provide flat surfaces 100 which constitute'supporting surfacesfor receiving the valve when in its upper and open position as shown inFigures 9, 18 and 19.

The cylindrical shell 34 has secured therein an annular valve seat 102against which the valve 104 is adapted to be resiliently urged.

The valve 104 as best seen in Figure 12, has an outside diameter whichis slightly less than the bore of the cylindrical shell 34 to provide aworking clearance. The differences which exist between the valve element104 of the present invention and that of the prior patent are that thelugs 106 and 108 integrally formed with the back side of the valve 104are in the form of gear teeth for cooperation in the recesses 90 of thearcuate plate 68. Cam plates 110 and 112 are secured to the inner facesof the lugs 108 and 106 and are adapted to engage the inwardly extendingpins 96 and 98, as seen best in Figure for controlling the initialmovement of the valve 104 towards its open position. Openings 114 areformed through the cam plates 110 and 112 and the lugs 106 and 108 for apurpose to be hereinafter described. The valve 104 is also provided witha pair of outwardly extending lugs 116 which are adapted to be receivedin the arcuated elongated slots 118 formed in the shell 34.

The means for resiliently supporting the valve 104 is comprised of apair of link arms 120, see Figure 5, which are of angulated constructionand have their free ends'provided with enlarged heads 122 forpositioning within the recesses 66 on the plungers 62. The opposite ends126 of the link arms 120 are angulated for positioning within theopenings 114 of the valve 104, as shown in Figures 5 and 11, forpivoting support of the valve disk.

Looking once again at Figure 12, the back side of the valve disk 104will be seen as having a pair of faces 130 and 132 divided by alongitudinally extending ridge 134, the faces 130 and 132 tapering to athickened portion at the central part of the valve disk and whereby thefluid flow past the valve disk will be substantially streamlined.

The operation of the valved coupler mechanism and insert means is bestshown in Figures 13 through 21 as a 4 the valve moves from closedposition to open position and then again back to closed position. InFigure 13, the valve 104 is seated and the male insert 12 of the conduitsection 16 has advanced so that the forward projecting edge 150 iscontacting the lower part of the valve disk 104.

In Figure 14, the male insert has moved forwardly so that the valve ispivoted slightly from the annular seating ring 102, the upper portion ofthe valve remaining in abutment with the seat. The fulcrum lugs 22 areengaged in the arcuate slots 152, see Figure 9, in the face of the valvedisk. The fiat portions of the camming plates 110 and 112 are disposedbelow the lugs 154.

Figure 15 shows the movement of the male insert farther into the femaleinsert with the valve disk 104 supported on the lugs 22 and the forwardedge 150. The camming surfaces 78 and are now in abutment with thebackside of the upper portion of the valve disk 104.

Figure 16 shows the valve disk 104 beginning its pivoting movement aboutthe lugs 22 the cam teeth 106 and 108 beginning to engage in the camrecesses of the arcuate plate 68. The backside of the valve disk 104 isalso engaged by the forward end of the arcuate plate 68 at 69.

In Figure 17, the movement has progressed substantially farther and thevalve disk is almost to its open position, with the cam lugs 106 and 108almost com pletely received within the recesses 90. In Figure 18, thevalve has reached the full open position and has its back face restingagainst the supporting surface 100.

In Figure 19, the closing movement has commenced although the valve diskremains in substantially a horizontal position. The only movement whichdoes occur is the axial movement of the valve and the lugs 106 and 108within the recesses 90.

In Figure 20 the male insert has been retracted a considerable distanceand the cam plates and 112 are now engaged with the inwardly extendinglugs 154, thereby effecting pivoting movement of the valve disk aboutthe lugs 22. Figure 21 shows the completed retraction of the maleelement with the valve disk 104 again seated against the annular seatand held thereagainst by means of the resilient supporting meanshereinabove described.

In the arrangement shown in Figure 1, it will be seen that the femaleinsert 10 is secured within the first conduit section 14 by means of theretaining ring 15, the insert being held from rotation by means of a pinor the like engaged in the recess 56. The male insert 12 is disposedwithin the second conduit section 16 and held from rotation therein bymeans of the pin 17 engaged in the slot 32. A coupling element 10 isprovided for securing the pair of conduit sections 14 and 16 togetherand for maintaining the first and second inserts in cooperation witheach other to maintain the valve in its open position.

In view of the foregoing description, taken in conjunction with thedrawings, it is believed that a device has been provided which willaccomplish all of the objects hereinabove set forth.
